-+ * I2C adapter driver for Intel IXDP2xxx platforms. This should work for any

-+ * SDA and SCL GPIOs have external pullups.  Setting the respective GPIO to 
-+ * an input will make the signal a '1' via the pullup.  Setting them to 
-+ * outputs will pull them down. 
-+ *
-+ * The GPIOs are open drain signals and are used as configuration strap inputs
-+ * during power-up so there's generally a buffer on the board that needs to be 
-+ * 'enabled' to drive the GPIOs.

-+ * . Simplify the interface between pci_auto and the rest: a single function.

-+ *
-+ * Further modified to include it as mips generic code, ppopov@mvista.com.
-+ *
-+ * 2001-10-26  Bradley D. LaRonde <brad@ltc.com>
-+ * - Add a top_bus argument to the "early config" functions so that
-+ *   they can set a fake parent bus pointer to convince the underlying
-+ *   pci ops to use type 1 configuration for sub busses.
-+ * - Set bridge base and limit registers correctly.
-+ * - Align io and memory base properly before and after bridge setup.
-+ * - Don't fall through to pci_setup_bars for bridge.
-+ * - Reformat the debug output to look more like lspci's output.
-+ *
-+ * Cloned for SuperH by M. R. Brown, mrbrown@0xd6.org
-+ *
-+ * 2003-08-05  Paul Mundt <lethal@linux-sh.org>
-+ * - Don't update the BAR values on systems that already have valid addresses
-+ *   and don't want these updated for whatever reason, by way of a new config
-+ *   option check. However, we still read in the old BAR values so that they
-+ *   can still be reported through the debug output.

-+    /* INSTRUCTION EMULATION
-+    *  ---------------------
-+    *
-+    * Nios II processors generate exceptions for unimplemented instructions.
-+    * The routines below emulate these instructions.  Depending on the
-+    * processor core, the only instructions that might need to be emulated
-+    * are div, divu, mul, muli, mulxss, mulxsu, and mulxuu.
-+    *
-+    * The emulations match the instructions, except for the following
-+    * limitations:
-+    *
-+    * 1) The emulation routines do not emulate the use of the exception
-+    *    temporary register (et) as a source operand because the exception
-+    *    handler already has modified it.
-+    *
-+    * 2) The routines do not emulate the use of the stack pointer (sp) or the
-+    *    exception return address register (ea) as a destination because
-+    *    modifying these registers crashes the exception handler or the
-+    *    interrupted routine.
-+    *
-+    * Detailed Design
-+    * ---------------
-+    *
-+    * The emulation routines expect the contents of integer registers r0-r31
-+    * to be on the stack at addresses sp, 4(sp), 8(sp), ... 124(sp).  The
-+    * routines retrieve source operands from the stack and modify the
-+    * destination register's value on the stack prior to the end of the
-+    * exception handler.  Then all registers except the destination register
-+    * are restored to their previous values.
-+    *
-+    * The instruction that causes the exception is found at address -4(ea).
-+    * The instruction's OP and OPX fields identify the operation to be
-+    * performed.
-+    *
-+    * One instruction, muli, is an I-type instruction that is identified by
-+    * an OP field of 0x24.
-+    *
-+    * muli   AAAAA,BBBBB,IIIIIIIIIIIIIIII,-0x24-
-+    *           27    22                6      0    <-- LSB of field
-+    *
-+    * The remaining emulated instructions are R-type and have an OP field
-+    * of 0x3a.  Their OPX fields identify them.
-+    *
-+    * R-type AAAAA,BBBBB,CCCCC,XXXXXX,NNNNN,-0x3a-
-+    *           27    22    17     11     6      0  <-- LSB of field
-+    * 
-+    * 
-+    * Opcode Encoding.  muli is identified by its OP value.  Then OPX & 0x02
-+    * is used to differentiate between the division opcodes and the remaining
-+    * multiplication opcodes.
-+    *
-+    * Instruction   OP      OPX    OPX & 0x02
-+    * -----------   ----    ----   ----------
-+    * muli          0x24
-+    * divu          0x3a    0x24         0
-+    * div           0x3a    0x25         0
-+    * mul           0x3a    0x27      != 0
-+    * mulxuu        0x3a    0x07      != 0

-+ * Semaphores are implemented using a two-way counter:
-+ * The "count" variable is decremented for each process
-+ * that tries to sleep, while the "waking" variable is
-+ * incremented when the "up()" code goes to wake up waiting
-+ * processes.
-+ *
-+ * Notably, the inline "up()" and "down()" functions can
-+ * efficiently test if they need to do any extra work (up
-+ * needs to do something only if count was negative before
-+ * the increment operation.
-+ *
-+ * waking_non_zero() (from asm/semaphore.h) must execute
-+ * atomically.
-+ *
-+ * When __up() is called, the count was negative before
-+ * incrementing it, and we need to wake up somebody.
-+ *
-+ * This routine adds one to the count of processes that need to
-+ * wake up and exit.  ALL waiting processes actually wake up but
-+ * only the one that gets to the "waking" field first will gate
-+ * through and acquire the semaphore.  The others will go back
-+ * to sleep.
-+ *
-+ * Note that these functions are only called when there is
-+ * contention on the lock, and as such all this is the
-+ * "non-critical" part of the whole semaphore business. The
-+ * critical part is the inline stuff in <asm/semaphore.h>
-+ * where we want to avoid any extra jumps and calls.

-+/* Core file format: The core file is written in such a way that gdb
-+   can understand it and provide useful information to the user (under
-+   linux we use the 'trad-core' bfd).  There are quite a number of
-+   obstacles to being able to view the contents of the floating point
-+   registers, and until these are solved you will not be able to view the
-+   contents of them.  Actually, you can read in the core file and look at
-+   the contents of the user struct to find out what the floating point
-+   registers contain.
-+   The actual file contents are as follows:
-+   UPAGE: 1 page consisting of a user struct that tells gdb what is present
-+   in the file.  Directly after this is a copy of the task_struct, which
-+   is currently not used by gdb, but it may come in useful at some point.
-+   All of the registers are stored as part of the upage.  The upage should
-+   always be only one page.
-+   DATA: The data area is stored.  We use current->end_text to
-+   current->brk to pick up all of the user variables, plus any memory
-+   that may have been malloced.  No attempt is made to determine if a page

-[PATCH] export linux/a.out.h
-
-Export linux/a.out.h like we do for asm/a.out.h. One minor complication is
-that the interesting stuff is protected by an CONFIG_ARCH_SUPPORTS_AOUT ifdef,
-so make sure this gets defined for unifdef.
